Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial application field" The present invention is provided, for example, so as to detachably or detachably attach a lid plate or the like to a container cap, a container, a clip, or a container body. Related to the equipment.

"Prior Art" As described above, there is an instrument provided with an upper plate such as a lid attached to and detached from a main body such as a container body in which the upper plate is elastically inverted with respect to the main body. . For example, in a cap with a lid plate, the lid plate is attached to the upper end portion of the rear surface of the peripheral wall of the cap body having the peripheral wall suspended from the peripheral edge of the top wall with a through hole through two bending portions provided with a small gap. An inverted L-shaped spring is installed between the outer surface of the peripheral wall of the cap body below the small gap and the upper surface of the intermediate portion of the lid plate in front of the small gap via the second and third bending portions, and the lid plate below the leaf spring. A so-called three-point hinge with a part removed is known.

"Problems to be solved by the device" In the conventional so-called three-point hinge elastic inversion mechanism, the cap body and the lid plate are directly connected by the hinge, so that the lid plate is an obstacle when pouring out stored items. However, there is a drawback that the mold structure for integral molding with a synthetic resin material becomes complicated.

Like the above-mentioned conventional example, the present invention does not directly bend the upper end of the peripheral wall surface of the cap body and the rear surface of the cover plate that closes the upper surface of the cap body, that is, hinge-connects the lower part of the rear surface of the peripheral wall of the cap body, etc., The upper plate as the lid plate is connected to the rear surface of the upper plate at both ends of a semicircular arc-shaped strip plate, and the first strip is formed in the middle of the strip plate.
A bent portion is provided, and instead of the inverted L-shaped spring of the conventional cap, a semi-circular plate spring is provided along the outer surface of the semi-circular band-shaped plate, and both ends of the plate spring are external surfaces of both ends of the band-shaped plate. What,
By connecting via the second and third bending portions, the upper plate is provided so as to be able to largely move to the lower rear portion of the peripheral wall when the lid is opened.

"Means for Solving the Problems" From the lower part of the rear surface of the peripheral wall 4 of the main body member, passing through the rear of the peripheral wall to the upper end of the rear surface of the peripheral wall, a strip-shaped plate 6 having a semi-arcuate shape and a first bending part 5 in the middle part And an upper plate 7 contacting the upper surface of the peripheral wall 4 is attached to the tip of the strip-shaped plate, and the second and third strips are provided along the outer surface of the strip-shaped plate between the base end and the tip of the strip-shaped plate. A semi-circular leaf spring 10 was installed via the bending portions 8 and 9.

[Operation] When the finger-holding piece 7a at the front end of the upper plate 7 is pushed up from the state shown in FIG. 1, the tip end of the leaf spring 10 is centered on the base end 6a thereof.
Although an attempt is made to move along the arc A, the third bending portion 9 connecting the tip end portion and the band-shaped plate moves along the second arc B centered on the first bending portion 5, so that there is elasticity. It will be stretched against and will be elastically restored after passing through the dead point. Therefore, the upper plate 7 is elastically inverted as shown in FIG.

"Example" The illustrated example shows a cap screwed to the neck of the container body.

Reference numeral 1 denotes a cap body, and the cap body hangs a peripheral wall 4 from a peripheral edge of a top wall 3 having a pouring hole 2.

A strip-shaped plate 6 having a semi-arcuate shape and having a first bending portion 5 at an intermediate portion is projected from a lower portion of a rear surface of an arbitrarily determined peripheral wall to a rear end of the peripheral wall to an upper end portion of the rear surface of the peripheral wall. An upper plate 7 is attached as a cover plate for opening and closing the upper surface of the top wall.

Further, on the outer surface of the strip plate 6, a semi-arcuate leaf spring 10 is installed between the base end portion 6a and the tip end portion 6b of the strip plate via the second and third bending portions 8 and 9. .

Although the device of the present invention is used as the cap in the above-mentioned embodiment, as shown in FIG. 4, the container main body which erects the peripheral wall 4 from the peripheral edge of the bottom wall 11.
The container may be composed of 1a and an upper plate 7 serving as a lid plate for opening and closing the upper surface of the container body, or other clips may be used.

"Effect of the device" Since the present invention has the already described configuration, when the upper plate is opened, unlike the case of the conventional so-called three-point hinge type device with the upper plate,
Since the upper plate 7 moves to a position away from the peripheral wall 4 of the main body member, the upper plate does not interfere with the use of the instrument, and when integrally molded with a synthetic resin material, the main plate is moved as described above. Since the molding may be performed in a state where the upper plate is moved to a position separated from the member, the integral molding is easy.
